Growth against the P/E multiple. Up and to the right is cheaper and faster — the quality-growth idea in one picture. Points beyond the axis are pinned to the edge and marked off-scale rather than allowed to compress everything else.

These two disagree on this pair: the Value pillar ranks cheapness against sector peers, while price-vs-fair-value is an absolute read. A name can be the better value in its sector and still the dearer one on cash flows.
The DCF is a cross-check on intrinsic value, separate from the quality-growth score above.

The companies
AZNAstraZeneca PLC
Why now
Drug Manufacturers - General · market cap $258.5b. Down 22% from 52-week high of $212.71 — deep drawdown territory. 10 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $213.99 (implying +28% upside).
Moat
Net margin 17% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. ROE 21% sits above Buffett's preferred 15% threshold — the equity base is compounding at a rate the market struggles to discount accurately. FCF converts 115% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
Trial-readout binary — late-stage clinical trials carry approve/reject outcomes that swing valuation 30%+; the equity is effectively a portfolio of these binary events, not a steady cash-flow business.

Where AZN and GSK diverge
On the headline score the gap is 25.4 points in favor of AZN. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.
- ValueAZN 67.5 · GSK 24.9AZN +42.6
- GrowthAZN 78.5 · GSK 65.0AZN +13.5
- QualityAZN 78.1 · GSK 85.3GSK +7.2
Pillars run 0–100 against sector peers, so a score is a statement about a company relative to its own industry rather than to the other name here. A wide Value gap usually means the market already prices the difference in quality or growth — which is the trade-off this comparison comes down to.
